Ok guys I was wondering if you could help me figure out what this noise is that only just started recently. It's a rather noticable 'rattle' or 'vibration' when the revs hit around 2500-3000 rpm. Anytime before and after that range the sound isn't there. When accelerating I can hear it when it reaches that rev range and also when downshifting around that rev range. I can also hear it in neutral when I give it some gas.

Could this be an exhaust leak somewhere or a really big problem somewhere else? I really can't afford to have a turbo go out on me right now.

Nevermind guys I found the culprit. One of the brackets on the cat had snapped and the heatshield was vibrating against the cat.
